Ganga saga part II: redesign dams, not rivers

Engineers require re-training, not the Ganga. This is where I had left our conversation last fortnight. Why did I say this? The inter-ministerial committee I participated in as a member was discussing how much the ecological flow—the water that should be left in the river for ecosystem and livelihood purposes—should be at all times. How much water is needed for the river to be a river; and not a drain?

Training engineers, not Ganga

Hydropower is important. But how important? Is it important enough to dry up stretches of our rivers? Or is there a way to balance the need of energy with the imperative of a flowing, healthy river? I have been grappling with these issues for the past few months. But now that the committee (of which I was a member) on the hydropower projects on the Ganga has submitted its report, let me explain how I see the way ahead.

Powerless and lost

The power blackout in northern India on two days should not be dismissed or misjudged. Analysts are jumping to conclude that the crisis was foretold. They blame delays caused by environment and forest clearance procedures and demand winding down the regulatory framework so that we can re-energise ourselves. Their other favourite whipping horse is ‘free’ electricity to farmers, which is said to be crippling the state electricity boards. These explanations are naïve and mistaken.

See the light

There is no question that India desperately needs to generate more power. The energy indicators say it all. It has the lowest per capita consumption of electricity in the world. This when access to energy is correlated with development, indeed with economic growth.
